As shown, the cover is of triplicate form, having a center leaf l6 and end leaves Hand I8 hinged to'the center leaf by flexible hinges I9 and 20 of any suitable construction; but it may be of duplicate form, or a single leaf may be used as a sup- 7 The two members 22 and-23 preferably corre--'- spond in length to the width of the pad to be held, but may be made in any'suitable form and of anysuitable material such as thin metal. In

the form shown in the drawings, each .of the members is right-angled in cross-section, and on spaced apart knuckles 28 (Fig.9) adapted to mesh between similar-knuckles on the other member to receive a hinge pin 3%. Along the hinged edges, the two members may'have registering cut-out portions or recesses 32, in which the springs 25 may be mounted on the hinge pin 3D-for holding the members closed.

On each end adjacent its free longitudinal edge, the upper member 24 is provided with a downwardly turned portion 36 having an inwardly turned sharpened edge or fin33 (Fig.1l) adapted to penetrate one side of aspad inserted in the clamp to hold it again stwithdrawal. Preferably-,ltlge 'QOLti6n 3B---iS"'in the form of an ear 'adapted to engage the side of the pad and the fin is formed on the forwardfedge thereof. Each fin is spaced at its upper end from the inner face of the upper member 24 a distance sumcient from the clamp.

to permit-a unit set of leaves to be withdrawn When a pad is inserted in the clampsas shown tain this result, the fins must be'inclined in the manner described. 'Inthe form of clamp shown,

the fins are perpendicular to that part of the clamp on which they are mounted which is permissible when the height of the clamp is some what greater than the thickness of the pad, since inv closed position, the fins are so inclined. If, however, the height of the clamp more nearly conforms to the thickness of the pad, the fins will have to be oblique in relation to that portion of the. uppermember 24 bywhich they are fastened to the hinged end of the leaf It, so that when thatleaf is folded over upon the center leaf l6, as shown in Figure 2, the clamp and pad are uppermost and the pad is exposed for writing. In such position, the leaf H is turned over in engagement with the bottom face of the center leaf. This latterleaf may be provided with upwardly turned side flanges 40 which.

its hinged edge is provided with a plurality of 3 the leaf "I8 is nested and held against lateral movement. I

Although the clamp may be used for holding any kind of a pad, it is particularly adapted for those pads made up-of a loose assemblage of separate leaves or sets of leaves which ar'e intended. to be withdrawn in their entirety from the clamp instead of being torn off a stub held by the clamp. When the pad is made up of sets of leaves, each set generally comprises a plurality of record leaves with one or more interleaved transfer or carbon leaves, all fastened together at one end and adapted to be handled as a unit. In Figure 5 of the drawings, such a set is, shown comprising three record leaves 42, 43 and 44, with two interleaved carbon leaves 45 and 46,

' all fastened together, at one end, by pasting or othe'rwisato form a stub 41. The leaves maybe provided with registering weakened or perforated lines 48,.permitting them to be detached from thestub. M

. Inpreparing the'bookfor use, the coveris opened up, asshown in Fig. 2, and a suitable pad is insertedinthe clamp 22 by raising the upper member through the medium of the finger grip .50, 'aftertwhichthe stub end of the pad is inserted in between the .two members of the clamp. The upper, member is then released and the Springscause it to close upon the pad and the fins to-bite into the opposite sides of thestub endv of the.pad,as shown in Fig 10. Thefins do not extend the entire thickness of the pad, but engage only. the upper portion thereof. The free edge of the lower member may be provided with a plurality of struck-up points 52 adapted to penetrate the bottom face of the pad for holding the bottom leaves against withdrawal. from the clamp; but these are not absolutely necessary, since the pressure exerted on the padby 1.111 the use of theibook, the leaf I! is turned back, exposing the top of the pad for writing. Whether itis turned over 'into engagement with the bottom face of the center leaf I6 or is inserted in the pad between the leaves which are to be :impressed with writing and the" leaves underneath, depends upon the 'character of the pad. 'If all -therecord leaves in the pad are of thin 'material, interleaved with carbon sheets, the leaf I! should be inserted between the top leaves which are to be impressed with writing, that is, the top leaf, and such additional copies asare to be made, and the leaves underneath, in. order to prevent -the writing from being carried through onto the underneath leaves. The leaf l1 serves as a stiff support to preventthis.

,If, however, the bottom'record-leaf 44 in'each set is made of paper, suchastag-board, which is of sufficient thickness to prevent the writing from being reproduced on the'underneath set, thenit'is unnecessary to insert the leaf I! in the pad, andit m'aybeturned over into engagement'with'the-bottom face of the center leaf l6.

' After the writing onthe topmost leaf has been completed, that leaf and the copies may be re moved from the clamp-by merely exerting apull on the free ends of the leaves. This pull causes the top ends of the leaves to travel upwardly on the fins and off their upper ends, releasing them for withdrawal from thecla'mp. This in no wise disturbs the underneath'leaves which are held downwardly-on thefins'by the free, longitudinal edge of the upper member, the pressure of which edge,""however, offers no appreciable resistance be filed temporarily between the leaves It! and '26, as illustrated by the leaf; 54 in Figure l, the flanges All serving to hold the filed copies secnrely between those two parts of "thecover. I -It will be observed that in a book made in accordance with my invention, the used leaves may be removed very rapidly by a mere pull without disturbing the remaining leaves of the pad. This eliminates entirely the difficulties heretofore experienced' in removing used leaves from manifold booksin which the pads are made up of loosely assembled leaves or sets of leaves, and thereby saves much time and labor on the part of the user. J
